This protein is of research interest primarily because it represents an important component in plant biology studies. The antibody targeting this protein (UniProt ID: Q0DB53) enables researchers to study protein expression patterns, localization, and functional analysis in rice, which serves as a model organism for cereal crop research . Understanding Os06g0602400 contributes to broader knowledge about plant development, stress responses, and potential agricultural applications through molecular characterization techniques.
Os06g0602400 Antibody is a rabbit-derived polyclonal antibody produced against recombinant Oryza sativa subsp. japonica Os06g0602400 protein. The antibody is supplied in liquid form with a storage buffer composed of 50% glycerol, 0.01M PBS (pH 7.4), and 0.03% Proclin 300 as a preservative . The antibody undergoes antigen affinity purification to ensure specific reactivity against the target protein. Due to its polyclonal nature, it recognizes multiple epitopes on the target protein, which can be advantageous for detection in various experimental platforms including Western blotting and ELISA applications.
The polyclonal nature of Os06g0602400 Antibody offers distinct advantages and limitations that should inform experimental design decisions:
Advantages:
Recognition of multiple epitopes increases detection sensitivity

Lysis buffer selection: Use milder detergents (0.5% NP-40 or 1% Triton X-100) to preserve protein complexes
Antibody coupling: Pre-couple antibody to Protein A/G beads or magnetic beads
Direct coupling via chemical crosslinking (using BS3 or DMP) can reduce IgG contamination
Pre-clearing step: Incubate lysates with beads alone to reduce non-specific binding
Antibody amount: Typically 2-5 μg per 500 μg of total protein lysate
Incubation conditions: 4-6 hours at 4°C with gentle rotation
Washing stringency: Balance between removing contaminants and preserving interactions
Elution method: Gentle elution with peptide competition or more stringent SDS elution
For co-immunoprecipitation (Co-IP) applications, additional considerations include:
Verification of complex integrity throughout the procedure
Reciprocal IP with antibodies against suspected interaction partners
Control IPs with unrelated antibodies of the same isotype
Mass spectrometry analysis to identify novel interaction partners
While Os06g0602400 Antibody has not been explicitly validated for IP applications, polyclonal antibodies generally perform well in IP experiments due to their recognition of multiple epitopes.

IP conditions: Use 3-5 μg antibody per 25 μg of chromatin
Controls:
Input chromatin (pre-IP sample)
Non-specific IgG IP (background control)
Positive control IP using antibody against known DNA-binding protein
Washing conditions: Progressively stringent washes to remove non-specific interactions
Analysis methods: qPCR for known targets or next-generation sequencing for genome-wide analysis
For Os06g0602400 specifically, researchers should first establish:
Whether the protein is expected to interact with DNA directly or as part of a complex
The nuclear localization of the protein through cellular fractionation studies
The efficiency of epitope accessibility after crosslinking
